Sintering is a thermal process (1300 1400 C) by which a mixture of iron ore, return fines, recycled products of the iron and steel industry (mill scale, blast furnace dusts, etc.), slag- forming elements, fluxes and coke are agglomerated in a sinter plant with the purpose of
The purpose of the sinter plant is to process fine grained raw materials into a coarse grained iron ore sinter, ready to be charged to the blast furnace. Sintering of fine particles into a porous clinker – sinter – is necessary to improve the permeability of the burden, making reduction easier. A high quality sinter has high reducability, which reduces the intensity of blast furnace ...
Sinter plants 73 030301 Sinter plants Process description By sintering, the pelletisation of fine-grained, smeltable ores, iron ore in particular, to compact lumps by heating nearly to the melting or softening point is understood. Melting tendencies at the grain boundaries lead to a caking of the material.
Iron ore sinter materials are an important feedstock material for the steel industry. Since fines cannot be used in conventional blast furnaces because they impair the upward gas flow, they are agglomerated in sinter plants, Gosh & Chatterjee [1]. Most steel plants use coal and iron ores from diverse sites as the major raw material
HIGH SINTER QUALITY AT LOW COSTS. Primetals Technologies is renowned for introducing state-of-the-art sinter plant solutions to the market. The latest developments include technology packages such as the Selective Waste Gas Recirculation system for reduction of off-gas emissions by up to 50%, or shaft cooler technology for zero emissions and energy recovery.
Investigations have been carried out at the three Corus UK sinter plants over the period 2002-2004 to characterise the emissions of both 2,3,7,8-PCDD/Fs and WHO-12 PCBs, to estimate annual mass releases of these organic micro-pollutants using the I-TEF and WHO-TEF schemes, and to investigate the formation of PCBs in the iron ore sintering process.
Modeling Sintering Process of Iron Ore 25 Fig. 2. Thermal cycle of the materials in the sinter strand. Several attempts have been done to predict the final properties of the sinter product (Water
What is Pelletization? The process of Pelletization helps converting Iron Ore Fines into "Uniform Size Iron Ore Pellets" that can be fed in the blast furnaces or in the DRI kiln (DRI). Why Pelletization? Pelletization is the only answer to a major...
an iron ore sintering plant revealed that the addi-tion of blue dust with red mud to the iron ore sin-ter mixture charge would overcome the problems arising from the RM addition to the sinter charge, like dilution of the sinter iron content, sinter qual-ity, strength and productivity [26]. Trushko et al.
Feb 04, 2021· The physical and chemical properties of the sinter are critical to the performance of the Blast Furnace. The cold strength of the sinter is measured as TI and hot strength as RDI. The Fe 2 O 3 in the iron ore is reduced to Fe 3 O 4 and then to FeO, with the help of heat supplied. In the iron ore sintering process, the heat is supplied majorly ...
Sintering is a process by which a mixture of iron ores, fl uxes and coke is agglomerated in a sinter plant to manufacture a sinter product of a suitable composition, quality and granulometry to be ...
Aug 19, 2019· Increasing the basicity index CaO/SiO2 between 0.1 and 3, chiefly through limestone admixture makes possible to reduce the thermal consumption of sintering and to improve the physical and chemical properties of the sinter. In the case of a plant using hematite ores, it seems interesting to produce an hyperbasic sinter and to complete the blast ...

FUNDAMENTALS OF IRON ORE SINTERING R. P. Bhagat INTRODUCTION The process of sinter making originated from a need to make use of fines generated in mines and in ore benefiCiation plants. With the development of sintering technology, a sintering plant has become a tremendous success for providing a phenomenal increase in
the sinter bed effectively which helps us in making good quality sinter. Productivity and quality are determined by the coke combustion behaviour during sintering process. Due to the density difference between iron ore fines and coke fines, coke fines form layer on the surface of raw mix balls / nodules.
Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace. The final product, a sinter,is a small, irregular nodule of iron mixed with small amounts of other minerals. Iron-process iron ore sintering process YouTube
required to produce 0.9 Mg (1 ton) of product sinter. 12.5.1.2 Iron Production - Iron is produced in blast furnaces by the reduction of iron bearing materials with a hot gas. The large, refractory lined furnace is charged through its top with iron as ore, pellets, and/or sinter; flux as limestone, dolomite, and sinter; and coke for fuel.
Jun 11, 2019· Sinter quality begins with the mined iron ore and the proper selection and mixing of the raw materials. Inhomogeneous raw mix can affect permeability and cause an increase in fuel consumption.
